2 folders are downloaded: no 1: the main rulebook & dungeon tiles. No 2: the counters, character cards, etc.
I normally use 210/220 GSM card (depends on what your printer can handle.

The rulebook is a 32 page PDF (30 are the actual content).

Ability/combat checks are 1D6 plus ability. Talents & situations can add modifiers.
The system is simple enough for younger players, and they should enjoy the look of the characters & monsters when printed out.

It's worth getting at the sale price (£6.42).
